'0 all whom it 777/(b;7/ concern:

Be it known that I, HENRY E. HUGHES, a etizen of the United States residing at Pawtuckt, in the county of Providenee anti State of Rhode Is1and, have invented certain-new anti useful Improvements in Spindies; and I do dec1are the following to be a full, c1ear, anti exact description of the nvention, such as wi11 enab1e others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, whiehform a part of this specification.

i\iy irwention relates to improvernents in spindles for spinning or twist-ing cotton or other yarns, in which a step having its 10 wer extremity shaped like a ba11 0r sphere is combined With a bolster, the upper extremity of which is similarly shaped like a ball or sphere, both step and bolster being supported upon conical or near1y conica1 shaped beds; and

the purpose of my invention is to provide a spindle which will yield readily to any change of tension in the yarn which is being spun or twisted thereon, and at the same time to provide an oil-reservoir which Will keep the parts of said spindle Which are exposed t0 fricton or wear constantly lubricated, and I accomp1sh these objects by the device show11 in the aecornpanying drawings, in which Figure 1 is an exterior view of myspindle; Fig. 2, a "ertica1 section through the middle thereof, and Figs. 3 and 4 the ball-terminated bolster and step, respectively.

The same parts are represented by the same letters throughout the various views.

In Fig. 1 A is the shaft of the spindle, B

the whirl, D the cap over which the whirl is p1aced anti which itseif slides into the outer jacket C. 0 is the base of the spindle integrai With C, and 6 is anut for fastening the spindle to its support upon the spinning-frame or other machine.

C is coned at the bottom interior] y,as shown in Fig. 2, D fitting therein in such'a manner as to be easi1y removed, but without any play between the two. \Vithin C is placed the support cl d, haring also a oonical interior, as shown in Fig. 2.

d is made exteriorly with an anglo 01 ring -v running around the same said ring forming the line of contact and support upon the conicalinterior of C, as shown in Fig. 2. The angle 7) is not sharp, but somewhat rounded, so as to allow son1e oseillation of the shank (l, t-here being considerable p1ay between the shank d and the interior of the 1ower part 0 6 is a tubular boister terminatng at its upper portion in the sphercal head e.

1) is bored out s0 as to admit the introduction of 6, the upper portion or neok of D hav- 'ing a larger bore than the lower portion for the purpose of aecommodating the spherical head e of the bolster, and the seat on which e rests being of rounded or oonica1 form. There is also left considerable space between the tubular portion of the step andthe surrounding wall of D, and the spherical head e aiso achnits of considerable osciilatiori in the lower portion of the bolster upon the applieation of any lateral pressure or force.

The conical depression in d sewes not only for a support for the step f, but aiso as an oil-reservoir, and the neck of the bolster e 'projects downwardly into this oil-reservoir, so that the porton of the spindle in contact with the bolster is alw ays amply lubricated. It will be seen that by reason of the conicai interior of C and the angular projection 01 ring t in contact With said conica1 exterior, together With the space about the shank (Z in the tube c, any change in the tension of the yarn, either by increase or decrease, will cause the upper portion of the shaft A to give or yieid quiekly and readily, being aided thereto by the spherical forms of the upper part of the holst-er e andthe lower part of the step f, and that the projecting shank (I will by force of gra-vity restore the shait A to a perpendicular position as soon as the increase 01 decrease of tension disappears.

This appears aiso :from the fact that the
